LLM Portfolio Lab

Objective

LLM Portfolio Lab is a research platform designed to systematically evaluate and compare LLM-generated investment portfolios under standardized, transparent, and reproducible conditions.

Each large language model (LLM) is given $100 in initial capital, fully invested, and is tasked with constructing a portfolio intended to outperform the S&P 500 over a full market cycle. The S&P 500 (proxied by SPY) serves as the benchmark for relative performance evaluation.
